That's kind'a what I was thinking. How do you get that close? I'm thinking of setting a branch into the ground and smearing peanut butter on it. I bet I get squirrels!
The squirrels will find it before the birds will.
I have feeders set up on post that the squirrels can't climb or jump on. I wire dead branches to the post above the feeders as perches. The bird usually land on the perches before feeding.
Also, I shoot mostly from a hunting blind on my deck or set up a remote camera.
